 * I have my blog runing on WordPress 3.2.1 without problem until all of sudden 
   today, the frontpage gives a blank page. It is not only frontpage, but all individual
   posts, pages, which need the front end would not display. I can still get into
   the admin page. The dashborad shows
    “Warning: array_keys() [function.array-keys]:
   The first argument should be an array in /home/mysitedomian/wp-includes/theme.
   php on line 521”
 * All posts and pages can still be seen and edited from admin page. However the
   dashborad Appearence menu show only the error below:
 * “Warning: array_keys() [function.array-keys]: The first argument should be an
   array in /home/mysitedomian/wp-includes/theme.php on line 521
 * Warning: uksort() [function.uksort]: The argument should be an array in /home/
   mysitedomian/wp-admin/includes/class-wp-themes-list-table.php on line 48
 * Warning: array_slice() expects parameter 1 to be array, boolean given in /home/
   mysitedomian/wp-admin/includes/class-wp-themes-list-table.php on line 55″
 * The edit under Appearence shows the ” the request theme does not exits”. The 
   plugins menu shows no plugin at all. When I connect to my account through FTP,
   all the plugins and themes are there. I removed all the plugins and themes apart
   from the default 2011, but the problem is not solved.
 * Should I re-install the wordpress? or there is something wrong with my database?
   I would really appreciate your advice.

 * Thanks for the reply. I removed all the themes apart from the default one. The
   problem is that wordpress does not see any theme or plugin, therefore it won’t
   be able display anything at front end.

 * Thanks. I will give it a go. Now I just found the same problem with my another
   wordpress blog in the same hosting under different domain names. I suspect this
   might be related to hosting setting up, but I am not sure. I will try to reinstall
   as you suggested.
